As a note, as long as both RAM modules are PC133, you can use that, too, but you're still limited to 2x256MB. PC133 seems to be more readily available for purchase and a good deal cheaper than PC100, so it's good to know.

Since this is an older machine, the performance can't be boosted very much. The maximum performance you can get from this machine is 1ghz processor, with 512mb RAM. The 1ghz processor is the biggest processor that is compatible, and unfortunately, the system is base on a 100mhz frequency rating, so PC100 memory is the only compatible memory available. The maximum chip size in PC100 is 256mb, they just don't make them any bigger, so 2x256mb=512mb RAM. As far as the hard drive, it is an IDE drive, and you can get an IDE drive up to 120gb. These are very good and durable machines, just slow, so if you can deal with the lower level of performance, this machine will last years. Also, these are upgradeable to XP pro, but not Vista.

Need info about series


The type of drive is IDE and 2.5- Inch for all those models.

T20, T21, T22, T23 --- 2647 all use the same IDE type of drive.

These you can buy for example in ebay. Search for laptop hdd ide 2.5inch or similar.

IBM ThinkPad T22 Series (Type 2647) memory upgrade


Hold on a second.. I have fixed a number of T21's and I recall that these units are super anal about the type of RAM they use. I am pretty sure that they require PC100 and will not accept PC133.

One second.... Ok, I just opened up my T21 and it has FRU 20l0255 which is PC 100. Here is a link to the specs. I have tried using PC133 and the same think happens - just does not boot. Nothing.

ThinkPad T22 will not boot to windows


I've seen several T20 series with the same problem. A CRC error pertains to a chipset on the motherboard, and the only way I've found to fix a CRC error is to replace the motherboard.

Your limited with the T20 series, the biggest you can go is 1ghz. Try the Pentium M chip, make sure that it's the same mhz (frequency) that's in it now, the board frequency matches the processor frequency. (either a 100 mhz or 133 mhz, you can tell by what memory it uses PC100 or PC133)
